(JavaScript) CSV Insert Column
Insert a new column into an existing CSV.
Note: This example requires Chilkat v9.5.0.89 or greater because the InsertColumn method was added in v9.5.0.89.
var success = false;
var csv = new CkCsv();
// Load the following CSV:
// Name;City;Weight
// John;Chicago;180
// Lisa;Denver;120
// Indicate that the 1st line contains column names.
csv.HasColumnNames = true;
success = csv.LoadFile("qa_data/csv/insertColumnTest.csv");
// We can insert a column before the 1st column.
csv.InsertColumn(0);
console.log(csv.SaveToString());
// The CSV now looks like this:
// ;Name;City;Weight
// ;John;Chicago;180
// ;Lisa;Denver;120
// Set the cells in column 0.
var col = 0;
csv.SetColumnName(col,"id");
csv.SetCell(0,col,"100");
csv.SetCell(1,col,"101");
console.log(csv.SaveToString());
// We now have:
// id;Name;City;Weight
// 100;John;Chicago;180
// 101;Lisa;Denver;120
// Insert a new column between City and Weight
// In other words, add a new column before the Weight column.
var weightColumn = csv.GetIndex("Weight");
console.log("Weight Column Index = " + weightColumn);
csv.InsertColumn(weightColumn);
console.log(csv.SaveToString());
// We now have:
// id;Name;City;;Weight
// 100;John;Chicago;;180
// 101;Lisa;Denver;;120
// Set the cells in the new column:
csv.SetColumnName(weightColumn,"Height");
csv.SetCell(0,weightColumn,"6' 2\"");
csv.SetCell(1,weightColumn,"5' 7\"");
console.log(csv.SaveToString());
// We now have:
// id;Name;City;Height;Weight
// 100;John;Chicago;"6' 2""";180
// 101;Lisa;Denver;"5' 7""";120
